Elfi-@Em spirit or soerioin-Q L o A sim9V citizen of the United residing zitounton City, in the county of iiuiielo,

Siete of 'lifiseonsinj here invented Certain new and useful 'improvements in Soruhloingiiiaohines; and i do hereby dechire the ioh lowing to he full? end exact descripr tion of me invention, such is will enable others siii inthe nrt to which it zipperand use the saine.

This inieiiiion reiiiies to improvements' in scrubbing machines.

The principal object of the invention is to pro zi ine-.chine through the medium oi which e door may he expe-litiousiy find cleaned.

netheiobiect oi toe i.A vent-ion is 'to provide a scrubbing machine in which erotary scrubbing brush is diiien by the support:- ting Wheels upon the Iorwerd movement of the machine, end depending ineens for drii# ingv the brush when the machine is posi tioned ifithin corner or in fact inany other place Where e forward movement @zur thorough ly scruhhed and not he ininerteo thereto.

ji former object oi the invention is to provide a scrubbingmachine of theeliera ter described in which e. novel mechanism is employed fo reciprocating trie scrubbing brush iongitiL finally of its supporting' shaft. i stili further object of the :invention is o provide e Amachine for the purposedesorioed which is Composed of i minimum number of @ori-s, is therefore simple in construction, and is Chee-ip to manufacture.

other objects in View? the invent. iii certain novel features of consi? n vion and combination of parts hereineit r fully described, illustrated in the eoeonigmnving drawingsa and pointed l in hereto appended; it being d t ist 'various Changes in' the ifoino n.f size and minor details of oonsgruc'ti n within the seopeoi the elaine, may be resorted, to Without departing i'romilie any of the advantages ne invention.

Lilie reference numerals designate corresponding ports in eli the giires of the drawings,

Referring to the'drawings, tne invention includesswcasing designated as s Whole by the reference letter A. This easing is preferably formed of sheet metal and includes .5, e front Wall G and. a rea-r side Walls?) Well 7. The front Wall has its lower edge disposed above and in spaced relation to the lower edges oi the 'side Wells, and has its upper portion extending over and partially` forming a top for the casing. closure element 8 of any suitable type is "ingedly connected 'to the rear Wall 7.

Disposed Within the. rear portion of the easing A is zi Water tank B which includes e bottoni. 9, sides lO-lO, a rear wall 11 and i, front Well 12, the front Wall being disposed in spaced relation to the front Wall 6 or" the casing. This tank is dislosed below Vthe closure 8 so as to permit Water being readily placed within said: tank. The side wells llil of the tank are disposed equidistant from the sidewalls 5 o' the casing, end .fire held in such relation by specing elements l3-i3- The rear vail il of the tank is-eonneeted to the rear "wall 7 of the Casing by rivets or other suitable means.

Located in the resi' portions oi' theA side wells 5 or' the easing are bearings 14T-1li, and joiiinaled in said. hearings is a transversely disposed supporting arie 15 oonstitiiting a drive shaft and having ground Wheels i6-16 mounted on the outer ends thereoi1 beyond the easing. drive shet passes through suitable openings i the side l o1q the tank, and a sleeve Il? is disposed around. the azie and ehe tank, end nes its ends enged, 18, and secured to the side Welle of *he driving means, 6 ise side' .This axle or veen 'ne ruspe@ :L bague??

Connected mesu is c L ahw@ a H nottata@ walls .3 ot the casing and carries a hand grip on at its outer end tor facilitating;r the turning ot' the rod. Y

Centrally formed in the front wall 12 ot' the tank l is an opening GT which extends entirely across said wall. A downwardly inclined scoop tStS is disposed in advance oi the iront wall l2 and between the side wallsof the casing'` the upper end being connected to said trout wall l2 of the tank at the bottom ot' the opening (ST and the lower end being' disposed below and directly in rear of the brush (l. A guard plate (S9 is disposed above the scoop G8, and is connected to the t'ront wal-l ot the tank l and also to the side walls 5 of the casing' A. Disposed within the tank B and secured to the iront wall 1Q slightly below the opening (S7 is a trough 70, the bottoni thereof being formed with a plurality ot' pert'orations 71. The rear wall ot this trough is extended to t'orln a diverg'ing lip Openings Tl-7 are 't'ornied in the side walls l() ot the tank and register with thel trough T0. Disposed between the sidewalls 5 and 10 ot the casing and tank are short troughs4 Tl which are so arranged as to register with the openings` T3. The rear wall of each trough T4 extended to torni a forwardly extending lip T5. lt will thus be observed that as tne machine lnores forward, the trough 72% will be rotated so as to draw the water and dirt along the scoop through the openingl and into the tank B. Portions ot' said water drop into the trough lt) 'troni whence they will pass through the pertoiationsI T1 into the tank, the lips 75 otl the second mentioned troughs servirte as guards to prevent such water and dirt: troni passingf therebeyond. By reason ot the tact that the lip TQ ot' the trough Tt) is disposed between the water in the tank and the opening 6T, all tendency ot' said water to pass-out through the opening when the machine is being operated will be prevented. as will be readily understood. A

ln order to push the niachine forwardly, l have provided a handle Tt which is on neited at its lower end to a sectional bail TT, the ends ot the hail being pivotally conuccted, as at 79. to the side wallsl 5 ot the casing.

ln order to actuate the brush t' when the nnu'hine is stationary, the following' inachanisni is employed: Fixedly mounted upon thc end ot the shatt 2t." opposite the pinion i l lo, 1s a pinion l.) which is engljag'ed by a large pinion 8O that is connected te the shaft el by a ratchet (not shown). Carried by the pinion 90 is a, sprocket wheel 8l. which is driven by means ot a chain 82 from a sprocket wheel 875 loosely mounted upon thev axle or drive shaft l5. Carried by the sprocket wheel S3 is a ratchet wheel 84;, the teeth S5 thereof being engaged by a gravity pawl St) which is pivotally connected to an arm til carried by the bail 7T ot the handle T6, said arm S7 riding in an arcuate slot 88 formed in the side wall 5 of the casing A, Isaid slotv being concentric with the pivot 7S ot the handle. l'twill thus be Observed that when the idler 49 is disengaged troni the pinion et? and 48, the forward drive of the brush is interrupted. This permits ot' the handle TG to be reciprocated and by means of the pawls SG engaging the teeth 85, the sprocket wheel 83 will be rotated, which through the inediuin ot the chain S2 and pinions Tf) and St), will cause the brush (l to rerolre in the saine direction. ln order to positively hold the idler i9 from engagement with the pinions i7 and 4S the pull rod 5G is Vt'orlned with a projection 89 which is adapted to engage the front wall T of the casing, and thereby retain the idler `in itsI inoperative position and against the tension ot the spring 555. ldihen it is desired to operate the brush upon the .toi-ward movement. of the machine, the idler #i9 is returned to its operative position, and inasmuch as t-he sprocket wheels Sl and S3 are loosely mounted upon the respective shafts, all danger ot' bindungr will be avoided.

What is claimed is:

scrubbing;- inachine, including a. frame, supporting wheels therefor, a handle pivotally connected thereto, a cleaning tool carried by the traine, connections between the traction wheels and the toot whereby the saine is operated during;A inorenient the traine; means to disconnect the toottroin the traction wheels, and means carried by tht` handle and trame adapted on oscillation i ot the handle to operate the tool when the latter' w heels. u
